In celebration of the iconic Serious Sam franchise’s 25th anniversary, the developers at Croteam have delighted fans with a special treat.
As a unique gift to the community, they’ve released the “Serious Sam Sketchbook” – an old, dusty collection of early concept art and sketches from the very first Serious Sam game. This special material can now be found directly within the installation folders of Serious Sam: The First Encounter and Serious Sam: The Second Encounter.
Furthermore, Croteam announced that Steam collectible cards and other items will soon be introduced for both classic titles: Serious Sam: The First Encounter and Serious Sam: The Second Encounter.
